CONTINUOUSLY-VARIABLE-RATIO TRANSMISSION OF THE TOROIDAL-RACE ROLLING-TRACTION TYPE.

摘要

A roller control system for a continuously-variable-ratio transmission (CVT) of the toroidal-race rolling-traction type. The system includes an operating mechanism having a first part (5, 6) operable to control the position of the roller centre along the torus centre circle but incapable of defining the tilt angle (36) adopted by the roller (7), and a second part comprising a mechanical link (13) connected to the roller bearings and operable to control the tilt angle (36). The link (13) lies substantially parallel to the plane of the roller (7) and is constrained to pass through a predetermined single point (14).
